He'd be an upgrade at safety. Not sure how expensive he'd be however. From PFT:
"We noted last month that Rams safety O.J. Atogwe was due an $8 million roster bonus on February 21, and there was next to no chance the Rams would pay it.
The Rams made the final decision a few days before the deadline, dropping Atogwe on Friday according to Jim Thomas of the St. Louis Post-Dispatch."
